GENX™ high bypass turbofan engines

The GEnx is the workhorse engine of the 21st century for All of these improvements are thanks to the incorporation medium and large-capacity, long-range aircraft, thanks of advanced and proven technologies from other engine to its tremendous improvements in efficiency and low families and on-going R&D programs. Like lightweight, cost of ownership. durable composite materials and specialized coatings. An innovative, clean-burning combustor, a counter- The GEnx is delivering up to 15 percent better specific rotating architecture. And a fan module that’s virtually fuel consumption than the engine it replaces, helping maintenance-free. operators save whenever they fly. It’s designed to stay on wing 20 percent longer, while using 30 percent fewer Designed around our customers’ needs, the GEnx parts, helping to keep maintenance costs in check. The represents a giant leap forward in propulsion technology. GEnx’s emissions are up to 95 percent below current regulatory limits, ensuring clean compliance for years to come. It is the quietest, most passenger-friendly commercial engine GE has ever produced. GENX™ high bypass turbofan engine Applications
